Title: 67 brake master cylinder
Post by: preaction on October 25, 2015, 10:18:42 PM
Is there a difference between a master cylinder used on  power, non power and drum/ disk applications.

Yes there are different applications.

Believe ( if I recall correctly) there is a difference in piston and bore size. Of course disc verses none disc the major visual difference is the size of the fluid bowls.

Would a  67 power disk master cylinder have a piston stop also ? Has anyone seen a identification paint stamp such as the letter M on the master cylinder.

I have seen the letter "M" stamp on original factory  master cylinders.  My original 67 MC has "M" stamped on the end away from the booster.  The 67 shop manual indicates M is for Mustang/Cougar application.   It isn't painted on, however.

What is the significance of a master cylinder with a small raised bump at the top of the boss for the  front line (front of car) of the master cylinder. I have seen this discussed elsewhere do these come into play with mustangs.

It is one of the distinguishing features of a assemblyline Master cylinder when discussing a Mustang Master cylinder.

It's the area where the fluid activated brake light switch was mounted for 64 (and earlier) Fords. It's kind of like the appendix (the medical version) of cars.

Would that be for a 67-68 only ?

I see that this is a older thread but suprissingly there are not many threads supporting this issue, I found a master cylinder from a 68 power disk equipped car with the correct stop bolt and the cast iron  riser at the front of the master cylinder it also has a few numbers neatly stamped on the side towards the drivers fender, C8075 AT is this common or is it a sign of something other than a assembly line part ?

I do not find the metal stamped numbers like  C8075 At and sometimes other numbers on all masters. I have taken apart many virgin assemblyline masters that did not have any numbers stamped on the side.  I am not sure what the numbers mean but given they vary and are not on all assemblyline type masters I am skeptical that they are done at Bendix indicating assemblyline.

From my notes on the master cylinders it looks like Bendix started stamping the date codes in the sides starting in 1969 as well as the manufacturing information.  That may explain why some of the original earlier master cylinders have no stampings on them at all.  Date codes would be in a Julian calendar format on the side, just like they were using on the bottom.  Bottom of the master is the casting date and the side is the assembly date.
